RPM T-Maxx 2.5R 3.3 A-Arms Blue Suspension Parts Upper Lower RPM80465

Overview

The RPM T-Maxx 2.5R & 3.3 A-Arms in Blue (RPM80465) represent the latest evolution in suspension components for Traxxas T-Maxx monster trucks. Whether you're a dedicated RC enthusiast running a T-Maxx 2.5R or 3.3 model, or you're searching for genuine replacement parts to keep your RC car UK collection in peak condition, these A-arms deliver the engineering excellence that RPM is renowned for across the RC hobby community.

As the newest generation of T-Maxx models adopted Revo-style axles with significantly larger diameters than previous versions, this created clearance issues with older A-arm designs. RPM engineered these new A-arms specifically to address this challenge, incorporating dedicated axle clearance zones that eliminate interference whilst maintaining the structural integrity and performance characteristics that make RPM parts the choice of serious RC bashers and racers throughout the United Kingdom and beyond.

Built with RPM's proven track record for durability and innovation, these A-arms are lighter than ever before, yet stronger than many aluminium alternatives you'll find elsewhere. They're available in the same colour options as the original T-Maxx A-arms and come backed by RPM's industry-leading breakage warranty—the best in the business. If you're serious about keeping your Traxxas T-Maxx running at its best, these are the A-arms to trust.

Key Features

• Revo-Style Axle Compatibility — These A-arms are specifically designed to accommodate the larger diameter Revo-style axles found on the T-Maxx 2.5R and 3.3 models, eliminating the clearance interference problems that plagued older A-arm designs on these newer trucks.
• Integrated Axle Clearance Zones — Precision-engineered clearance areas are built directly into the A-arm geometry, ensuring smooth operation and preventing binding without compromising the component's strength or durability.
• Lightweight Construction — RPM has achieved a new benchmark in A-arm weight reduction whilst maintaining or exceeding the strength specifications of comparable parts, contributing to improved handling, faster acceleration and reduced wear on drivetrain components.
• Superior Material Science — Manufactured from RPM's proprietary polymer compound, these A-arms deliver strength comparable to or better than many aftermarket aluminium A-arms, whilst remaining significantly lighter, offering the best balance of performance and durability for RC car enthusiasts in the UK and worldwide.
• Rugged Durability — Engineered to withstand the extreme stresses of off-road bashing, racing and competitive driving, these A-arms maintain their performance through countless impact events and harsh conditions.
• Industry-Leading Warranty — Backed by RPM's renowned breakage warranty—the best in the business—giving you confidence that your investment is protected against defects and failure.
• Colour-Matched Design — Available in blue to match the same colour palette as original T-Maxx A-arms, allowing you to maintain a cohesive appearance across your suspension components.
• Factory-Optimised Geometry — These arms are engineered by RPM with the exact specifications and geometry needed for T-Maxx 2.5R and 3.3 vehicles, ensuring perfect fit and performance without modification.

Technical Performance

The RPM T-Maxx 2.5R & 3.3 A-Arms represent a significant advancement in suspension component engineering for modern Traxxas monster trucks. Built from RPM's advanced polymer material, these A-arms deliver exceptional performance through a combination of lightweight construction and genuine strength. The introduction of axle clearance zones addresses the specific engineering challenge posed by the larger diameter Revo-style axles fitted to the newer T-Maxx generation, ensuring smooth articulation without binding or interference. Unlike many aftermarket solutions that compromise either weight or strength, these arms achieve both objectives simultaneously. The material composition provides flexibility under load whilst maintaining dimensional stability, crucial for maintaining consistent suspension geometry during aggressive driving. RPM's manufacturing process ensures tight tolerances and consistent quality across every component. Whether you're running your T-Maxx 2.5R or 3.3 for competitive racing, weekend bashing sessions, or regular recreational driving, these A-arms will maintain their performance characteristics across thousands of driving cycles. The lightweight construction means reduced unsprung weight, which directly translates to improved handling response, faster acceleration and better overall vehicle dynamics. For RC enthusiasts in the UK and beyond seeking genuine performance upgrades or reliable replacement parts, these A-arms represent genuine value backed by RPM's proven reputation for quality and durability.

Frequently Asked Questions

• Are these RPM A-Arms compatible with my Traxxas T-Maxx? — Yes, these A-arms are specifically engineered for the T-Maxx 2.5R and T-Maxx 3.3 models. They feature dedicated axle clearance zones to accommodate the larger diameter Revo-style axles fitted to these newer generation trucks. They are not compatible with older T-Maxx 2.5 models which use different axle dimensions.
• Why would I need new A-arms for my T-Maxx? — You may need to upgrade if you're experiencing suspension binding, clearance issues with the newer Revo-style axles, or if your existing A-arms have suffered damage or breakage from aggressive driving or racing. Additionally, newer RPM A-arms offer lighter weight and improved geometry compared to older designs, resulting in better handling and performance across a wide range of driving conditions.
• How many A-arm packages do I need? — A complete T-Maxx requires four A-arm assemblies total (one per corner). Each package RPM80465 contains one upper and one lower A-arm, so you will need to purchase four packages to equip your entire truck with new A-arms.
• What makes RPM A-arms better than aluminium alternatives? — RPM's proprietary polymer material delivers strength comparable to or exceeding many aftermarket aluminium A-arms, whilst remaining significantly lighter. This lighter weight improves handling response and reduces stress on other drivetrain components. Additionally, RPM A-arms are backed by the industry's best breakage warranty, and they offer superior flex characteristics under load, contributing to better overall suspension performance and durability in real-world driving conditions.
• Are these suitable for beginners? — Yes, if you already own a Traxxas T-Maxx 2.5R or 3.3, these replacement A-arms are suitable for any skill level. However, installation requires basic mechanical knowledge and appropriate tools. If you're unsure about installation, we recommend contacting RC Model Shop for guidance or professional installation support.
• Do these A-arms come with a warranty? — Yes, these RPM A-arms are backed by RPM's industry-leading breakage warranty, the best in the business. This protection gives you confidence in your investment and demonstrates RPM's commitment to quality and durability.
• What is the difference between these new A-arms and older RPM T-Maxx A-arms? — The key difference is that these new A-arms feature integrated axle clearance zones specifically designed to accommodate the larger diameter Revo-style axles on the T-Maxx 2.5R and 3.3 models. Additionally, they are lighter than ever before whilst maintaining strength comparable to or better than many aluminium alternatives. Older A-arms (such as models #80071-#80078) were designed for earlier T-Maxx generations with smaller diameter axles and will experience clearance interference with the newer Revo-style axles.
